Here’s something single woman already know, single men STINK. And not metaphorically, we literally smell terrible. Now it’s not because single men have worse hygiene . . . I mean . . . they probably DO, but that’s not the reason. It’s because single men produce more testosterone, which leads to a nastier body odor. A new study out of Australia asked women to smell a bunch of single men’s shirts and married men’s shirts. And even though the married men’s smelled better, the women were more attracted to the single men’s. Researchers say this shows women have evolved a way to “sniff out” single men, so they’re not wasting their time on someone who’s unavailable.
